分析杂一代荷斯坦成年母牛体尺指标与体重的相关性,并进一步进行估测体重的回归分析,指导黄牛改良的生产实际及选育工作。以门源县麻莲乡2008年测量的495头杂种荷斯坦牛相关数据为基础,分析体重与体高、体长、胸围、管围的相关系数,构建估测杂种荷斯坦成年母牛体重的回归模型。结果表明:体重与体高、体长、胸围、管围的相关系数R分别为0.712、0.785,0.889,0.514;得到了估测体重的最优回归模型,Y=-648.399+3.317X3+2.062x2+1.211x1(P〈0.01)(R2=0.877)。杂种荷斯坦成年母牛体重与体高、体长、胸围、管围存在明显的线性关系。
分析雜一代荷斯坦成年母牛體呎指標與體重的相關性,併進一步進行估測體重的迴歸分析,指導黃牛改良的生產實際及選育工作。以門源縣痳蓮鄉2008年測量的495頭雜種荷斯坦牛相關數據為基礎,分析體重與體高、體長、胸圍、管圍的相關繫數,構建估測雜種荷斯坦成年母牛體重的迴歸模型。結果錶明:體重與體高、體長、胸圍、管圍的相關繫數R分彆為0.712、0.785,0.889,0.514;得到瞭估測體重的最優迴歸模型,Y=-648.399+3.317X3+2.062x2+1.211x1(P〈0.01)(R2=0.877)。雜種荷斯坦成年母牛體重與體高、體長、胸圍、管圍存在明顯的線性關繫。

Correlation of The body size index and body weight of adult Holstein female cattle was studied for further regression analysis of body weight and breeding. Based on statistics of 495 adult Hotstein female cattle in Malian township,Menyuan aunty in 2008. Establishing relate coefficient of body weight and body height, body length, chest circumference for building regression model of estinating body weight. The results showed that correlation coefficient (R) of body weight and body length,chest circumference is 0.712,0. 785,0. 889 and 0.514 respectively, optimol regression model is,Y = -648.399 +3.317 X3 +2. 062X2 + 1. 211X1 ( P 〈 0. 01 ) ( R2 = 0. 877 ) ,There is linear relationship between body weight and body weight,body length,chest circumference.
